I need your help with solving this problem.
My UIImage is allowed to be moved around the screen using PanGesture and it also has TapGesture to rotate with trasform
.transform.rotated(by: CGFloat(M_PI_4))
After user is done with positioning and rotating, he clicks the UIbutton to show a four dots in corners of the Image
//dotcode
let dotSize = 20
let firstDotView = UIView()
firstDotView.frame = CGRect(x: 0, y: 0, width: dotSize, height: dotSize)
firstDotView.backgroundColor = UIColor.black
firstDotView.layer.cornerRadius = 10
view.addSubview(firstDotView)
1: dots like that, don't have any connection with green space
Dots always show in the corner

I'm trying to display an NSImageView with a symbol icon inside it, however the top and right sides are being clipped off. I tried changing the imageScaling, imageAlignment, bounds, and image.size, but it says the same.
Here's what I'm doing right now:
let iconImage = NSImage(named: .myImage)!
let icon = NSImageView(image: topBarButtonIcon)
icon.frame = CGRect(x: 7.5, y: 7.5, width: 15, height: 15)
icon.animates = true
icon.isEditable = false
icon.imageAlignment = .alignCenter
icon.imageScaling = .scaleAxesIndependently
Here's how it shows up:
This might matter: I'm sub-viewing the icon into a custom NSButton class I made, it's given a 30x30 frame, but even if I change it to something like 100x100 the icon says clipped.
I insert a UIView into a UIButton with following code:
let backgroundView = UIView()
backgroundView.backgroundColor = .red
backgroundView.translatesAutoresizingMaskIntoConstraints = false
blueButton.insertSubview(backgroundView, at: 0)
NSLayoutConstraint.activate([
backgroundView.leadingAnchor.constraint(equalTo: blueButton.leadingAnchor),
backgroundView.trailingAnchor.constraint(equalTo: blueButton.trailingAnchor),
backgroundView.topAnchor.constraint(equalTo: blueButton.topAnchor),
backgroundView.bottomAnchor.constraint(equalTo: blueButton.bottomAnchor)
])
The promlem is that the backgroundView covers the whole button and I only see the red field instead of the button (its an image) with a red background (my subView).
This is the storyboard part of my image. I don´t do something else in the code with this buttons with the exception of trying to put a subView into:
My goal is to have a circle background like in the picture below. For example the red circle button has a rounded red (but brighter than the buttons red) backgroundView.The standard background of the button should stay the same.
I also tried to send the subView into the background but it didn´t work for me:
blueButton.sendSubviewToBack(backgroundView)
I reduced the alpha value of the subview to see if the button image is still there.
for view in blueButton.subviews {
view.alpha = 0.5
}
And it is:
How can I solve this problem?
Do not inject extra subviews into a button. If the goal is to make the background color of the button red, set its backgroundColor to .red. If the goal is to put something behind the button image, that is what the backgroundImage is for. Or just make the button image look like the image you really want.
I made this button:
It looks a lot like your picture. Here's the code:
let im = UIGraphicsImageRenderer(size: CGSize(width: 30, height: 30)).image {
ctx in
UIColor.red.withAlphaComponent(0.2).setFill()
ctx.cgContext.fillEllipse(in: CGRect(x: 0, y: 0, width: 30, height: 30))
UIColor.red.setFill()
ctx.cgContext.fillEllipse(in: CGRect(x: 5, y: 5, width: 20, height: 20))
}
b.setImage(im.withRenderingMode(.alwaysOriginal), for: .normal)
I think that's a lot better than messing with unwanted illegal subviews.
I am trying to display a lock icon on the left hand side of a search bar's text field, like Safari displays when you visit a secure site, but I don't know how to set the frame.
How can you get the frame of the label within a text field?
Here's what I have:
let lockImageView = UIImageView()
lockImageView.image = UIImage(named: "lock")
lockImageView.contentMode = .scaleAspectFit
lockImageView.frame = CGRect(x: searchBar.bounds.midX, y: 23, width: 11, height: 11)
searchBar.addSubview(lockImageView)
Here's what it looks like because the frame for the icon is not correct:
Add this two to your searchBar before adding the image to the subview
searchBar.leftView = lockImageView
searchBar.leftViewMode = UITextFieldViewMode.Always
I have an NSButton, created programatically. within said button, I have an NSImage that serves as an icon:
let button = NSButton(frame: NSRect(x: 10, y: (200 + (50 * id)), width: 100, height: 50))
button.action = #selector(self.switchToView)
let img = NSImage(named: "wob_icon")
button.image = img
What I'm trying to do is get the image 10pt. from the left side of the button, while centred vertically. So far, the image shows up centered horizontally as well as vertically, but since it doesn't seem like I'm able to define a frame or something like that, I can't really move it.
Is there a way to move the image within it's parent (the button)?
Thanks.
Maybe you could use the imagePosition property on a NSButton? (documented here).
It uses an enum of type NSCellImagePosition (documented here) and allows you to set the image to the left of the text, to the right of the text, above the text, below the text and so on.
You still won't have the opportunity to align things pixel perfect but if you can live with that, then imagePosition seems like the way to go.
Here is how to use it:
let button = NSButton(frame: NSRect(x: 10, y: 10, width: 100, height: 50))
button.action = #selector(self.switchToView)
let img = NSImage(named: "wob_icon")
button.image = img
button.imagePosition = .imageLeft
button.title = "Look left :)"
And that gives me this stunning UI:
Hope that helps you.
Im making a small boxing app. This whole week iv been trying to work out how to solve my current problem above, with no luck :(.
Summary
Basically Its a 1 v 1 game. Each time the user hits the other player I want to make a tiny number pop up near him and float up and dissappear.
Its sort of like when you play MMORPG's and when you do dmg you see how much you did. See image below for an example!
So basically everytime the user hits the other player I want a little number to pop up on the screen to show the dmg and then float up and disappear.

I am building the game on a simple UIView
The label is a UILabel
Anywhere How I can achieve this?
Thank you!
Create a label, then use UIView.animateWithDuration to animate it.
let label = UILabel(frame: CGRect(origin: point/*The point where you want to add your label*/, size: CGSize(width: 50, height: 50)))
label.text = "+1"
label.font = UIFont()//Your font
label.textColor = UIColor.blueColor()
label.alpha = 1
self.view.addSubview(label)
UIView.animateWithDuration(1) {
label.center = CGPoint()//The point where you want your label to end up
label.alpha = 0
}
Edit: As mentioned in the comments, you asked for how to create the label at a random point. Try this:
let screenWidth = self.view.frame.width
let screenHeight = self.view.frame.height
let randomX = CGFloat(arc4random_uniform(UInt32(screenWidth)))
let randomY = CGFloat(arc4random_uniform(UInt32(screenHeight)))
let point = CGPoint(x: randomX, y: randomY)
As you will notice, for the width and height, I use the view's frame's width and height. You may want to use the view's bounds. For more on this, check out this SO Post.
